I went to the local blacksmith and picked up a couple of hot rolled steel rods to fit the down tube and seat tube sockets on a standard bottom bracket.


I put a taper cut on the ends of the rods so both of them can sit in the sockets at the same time, however how deep into the shell must they go? I assume as long as they are past the end of each socket it will be OK, however some input on this is appreciated.
